Great, easy-going platformer.
It reminds me of the camera-pan levels in Super Mario, minus the plumber and insane difficulty as you climb higher on the stalk. It becomes redundant when the player has to start from the bottom every play, though the implementation of a fair scoring system depends on having a clean slate each time, to be fair.
You could include levels in a sequel, I suppose? I'd be completely satisfied. In any case, incredible work.
